I've been using Thunderbird for several years now without any issues, and I currently have the latest version installed. I typically have multiple email accounts logged in. Recently, I tried adding a Gmail account, but it wouldn’t log in, showing the error: "Unable to log in at server. Probably wrong configuration, username, or password."

I’ve tried the usual fixes like closing and reopening Thunderbird, clearing cache files, and even searching online for solutions. Based on what I found, I’ve tried turning off VPN/antivirus, changing the default browser, clearing browser data, and, finally, uninstalling and reinstalling Thunderbird after removing all my email accounts.

Now, I’m unable to log in to any of my accounts, which were working fine before. Can anyone guide me on how to resolve this issue?

Thanks in advance!

Hi Folks,

As I said above, I just updated to Thunderbird version 128.2.1esr (64-bit) and seem to have lost a couple of functions, in particular the ability to make a new Tab, and the use of an extremely handy Add-on, Shrunked Image Resizer. I have Mac OS 12.7.6 and I noticed in the release notes for 128.2.1esr (64-bit) that this latest version's System Requirements are MacOS 10.15 or later. Does that mean that I should not have downloaded the latest version, and if so, how can I revert to an earlier version of TB that will allow me to use Tabs and Shrunked Image Resizer? I thought that Thunderbird was capable of recognizing which version of Mac OS I have and thus would not suggest I update to the latest version of TB if it won't work as it did with an earlier version of TB. I would be very grateful if you could suggest a solution to my problem.

Thanks, Chris O'Brien

Hi,

I use the latest Thunderbird email client 128.2.2esr (64-bit). Microsoft announced that to make it work with outlook all users have to make changes in settings for more security. I did all that they wrote and can receive emails on my .......@outlook.com email address, but I can't send emails due to absence of authentication setting for outgoing server. I attached screenshots FYI. Is it possible to fix this issue? It's required to add authentication setting for outgoing server.

Regards, Leonid.

Is it possible to use authentication with SCRAM-SHA-256 for SMTP and IMAP? I tried with the Thunderbird version 102.10.1 but failed to get that authentication. It doesn't seem to support SCRAM-SHA-256 from the error message. Could you please help me to solve this problem?

Canon Scanner issue with Thunderbird using MP network EX 2.0, I have 4 win 10 systems all using LiDe200 and 210 scanners with similar problems, 2 systems I can attach emails to Thunderbird only manually now as the Thinderbird email client isnt shown on the dropdown box only (None attach manually) and the other 2 systems cant send anything at all, comes up with the above and the with a message saying no program is accociated with it, even though Thunderbird is the default email client ............when I try to attached it to an email ............... I have NO IDEA how to fix this and I'm not technically very good either so need answers I can understand and do with out technical jargon I dont understand, I did ask a computer guy who does our systems but he didnt know what the problem was and had no solution for that. I am hoping you can help with it as I'm super frustrated with it, as it came on the back of another Thinderbird issue I have with security exceptions which defies being fixed. HELLLP !

Hi, Please see screenshot. The "From" field does not have my address and there is nothing to select in the drop down. I cannot type into the body of the email either. Also, when I click on "About Thunderbird" I do not get a pop-up window with version. I am receiving email. Thank you Cams

Hi

I recently updated to 128.2.1 esr and my message filters are not working. When I open "Tools" > "Message Filters" the filter list is empty but when I open the msgFilterRules.dat file on my profile the message filters are there. (I made lot's of them.)

Hi. Is there a way to add travel time to an appointment just like you can do in google or apple calendar? It’s a great feature. When I add an adres to my appointment Apple calendar will automatically add the travel time by car from my home to the destination. I miss that feature in Thunderbird.

Hi Thunderbird Support Team,

I recently installed the latest version of Thunderbird in a Hyper-V virtual machine and encountered the following message: " Approval required Mozilla Thunderbird This app requires your admin's approval to: Read and write access to mailboxes via IMAP. Read and write access to mailboxes via POP.

Allows the app to have the same access to mailboxes as the signed-in user via POP protocol.

This is a permission requested to access your data in xx Send emails from mailboxes using SMTP AUTH. Maintain access to data you have given it access to View users' basic profile"

This was functioning with the previous version of Thunderbird, but now my IT team requires additional information about what the app is trying to do with our Office 365 environment. The approval process is crucial because some apps may introduce security risks or seek extensive access to our Office 365 resources.

Could you please provide more detailed information on the permissions requested and the specific changes in this version compared to previous versions? This will help in getting the necessary approval from our IT team.

Thank you for your assistance.

Best regards, Jenny

Our email accounts are attached to our host domain name. We are going to be changing the host domain location from a smaller local provider to Spectrum Internet to service. The email addresses XXX@xxx.com 'will not change, only the server host location. As a backup, we are moving all existing emails located in subfolders under the email accounts to the LOCAL folder (creating new "trees" there) so they are in a permanent location to be unaffected by the server change. From my knowledge... we will not create new email accounts in Thunderbird .... only change the server location, ports, etc for that specific email. I want to confirm with others that this should be the plan?

Thanks for listening: Last week, Thunderbird began returning this message with each attempt to send mail: An error occurred while sending mail. The mail server responded: <tedcomo@chartertn.net> sender rejected. Please verify that your email address is correct in your account settings and try again. I have no problem receiving mail. At the same time, my wife began having the same problem on her laptop, which tells me either Charter, or Mozilla, changed something. I started with Charter. They told me to rename both servers to mobile.charter.net (outgoing mail was formerly smpt.charter.net. No effect. They then had me log into Spectrum and send a test mail directly from my account. It went through OK and they said the problem had to be on Mozilla's end. Any suggestions?

In Thunderbird calendar, on 27th Oct 2024, entries added are displayed one hour ahead of where they should be. If the entry is edited, the times are correct, and they show correctly in another calendar app (Calendar on my iPhone). The issue does not occur for events on the day before or the day after, and is the same for a newly added event as for an existing one.

See screen shots. You can see my test event displayed at 11:00 - 12:00 but on editing it is actually 10:00 - 11:00 - the latter is correct.

27th Oct is the day that DST ends in the UK (at 0200) in 2024, but the events are several hours after that.

Using TB 115.15. When I delete a number of messages, then empty the trash, I cannot delete another message until I restart Thunderbird. Is there a limit as to the number of emails I can trash prior to emptying the trash?

G'day from 'Straya!

I have migrated Thunderbird from one Windows laptop to another, copying the profile and all included files. This mostly worked but has created a couple of issues I am trying to troubleshoot and could really use some help.

First thing probably worth noting is that I had an earlier version of Thunderbird on the old laptop than the new one downloaded to the new laptop. I don't that if that is the problem.

I have two email accounts which are both using IMAP. When I delete an email in Thunderbird, it keeps coming back and I now have multiple copies of that email. My storage is filling up 😒 Is there a setting I am missing?

Additionally, the migration does not seem to have brought over my contacts. Did I miss something?

Any help and advice will be greatly appreciated.

With the latest Thunderbird update (128.1.0esr) I am seeing frequent "not responding" situations. It eventually does come back. Am I doing something wrong? I am on a PC running Windows 10.

My Thunderbird randomly stops checking for email messages, and will not even check when I click 'check' (the cloud). I have to dismiss Thunderbird and restart it.
